Outside paint finish

My 2016 has been sitting for over a year and the sun only hits one side of it. The side where the sun doesn't hit is like new, shiney. The other side shows some fading especially on the light green color. I have used rubbing compound and wax but it still doesn't give an even shine. I was a painter, so I'm suspecting that originally a clear coat was used on the paint. I am wondering if I should spray clear coat on that area. It would mean I would have to remove the synthetic wax and maybe go over that with a super fine sandpaper. Anybody know how to remove the wax? And what to use? I'm thinking alcohol but don't know. I'm thinking just let it go for now and do it in warmer weather. Any thoughts?

You did the right thing.  You just left off a step.  Rubbing compound is great to use if there is oxidation present.  Oxidation is when the blue or green has a whitish tint to it.  BUT do not wax it after as it will not give a shine.  You need to polish it.  Any marine gelcoat polish will do.  Then you need to wax it to protect the shine from the elements.  I would not touch it and risk damage to the surface.  I would just wait a couple months.  Then I would use a strong washing detergent and wash it down (even the claimed permanent wax only lasts six months).  Then I would skip the compounding step assuming the oxidation is not there and would go straight to polish.  An electric buffer would be better than by hand.  You should have a like new shine back.  Then you can wax it.  We did this before closing it up for the winter (we bought a cover) and it looks brand new. Hopefully it will look as good when we take the cover off in the spring

Yes the dealer told me it was a gelcoat when I asked how to keep it shining.  For that reason, rubbing compound is fine to remove oxidation.  But agree would not use it if there was no evidence of oxidaton and would just wash it, polish it and wax it.  Better to follow instructions for how to shine a boat rather than how to shine a car.  Lots of YouTube videos on how to do it.
